How to setup Docker-compose to isolate a web application — Each computer has a specific environment: some tools and specific version of languages are globally installed, our applications share databases… When we work on a web project, the production server might be different from our computer. This is error prone. Docker solves this problem by running applications in isolated environments. In this article, we are going to

How to use pure functions, closures and functions composition — In a previous article we went through the steps to Smooth a svg path with cubic bezier curves. Here, we are going to refactor this code with functional programming. Functional programming is the process of building software by composing pure functions, avoiding shared state, mutable data, and side-effects. From What is functional programming? by Eric Elliott

And a bit of trigonometry — While it is straightforward to draw straight lines in a Svg element, it requires a bit of trigonometry to smooth these lines. Let’s see how. Follow up article: refactor this code with functional programming. We have an array of tuples representing the points coordinates of a line. const points = [[5, 10], [10, 40], [40, 30], [60, 5], [90, 45], [120, 10], [150, 45], [200, 10]]

Setup a reverse-proxy, and, for each website running inside a Docker container, create an automatic nginx configuration and a SSL certificate. — Hosting multiple websites on a single Virtual Private Server is simple and efficient. Nowadays, HTTPS is a required feature for any website. Let’s see how to: Setup a nginx reverse-proxy and generate a nginx config for each website to link a domain name and a container.

A complete example — A modern web-app requires an environment to run JavaScript on a server and to request data from APIs running on other type of servers. Edit Apr 28, 2018: removed the deprecated links docker-compose instructions. Let’s make an example which does the following when the server receives a client request: An nginx reverse-proxy forwards incoming traffic to the appropriate server and directly serves static assets (images and scripts).

Three steps to configure the deployment process with a Git Hook. — Git is a great tool for version control, but not only. It can also simplify the deployment process, thanks to Git Hooks. Three steps to configure the deployment process: 1. Create an empty Git repo on the server 2. Write a Git Hook to deploy the code 3. Deploy from the local computer tl;dr On the remote server: # Copy the 'project-create.sh' bash script https://gist.github.com/francoisromain/58cabf43c2977e48ef0804848dee46c3 …
